The two upper sheets are tornoff against an edge 25'which is provided'onthe coverQafter they pass between the rolls, the lower sheet beingcarried forwardover an idler26, and then down to a storage rol] 27.Thisstorage roll must of course,1be driven and provision must'he madefor the'increasing diameter .of

the roll, as otherwise, the lower strip. of paper would befdrawn forwardat an increasing? speed. The operation of. the storage roll' isefectedthrough lgears'', 31, 32,

33 and. 34, the last namedfgear being carried on, the roll 15. This gear34 is cutaway at 35 .inorder that there may be no drive ofthe gear 33,and hencey of the storage4 roll, dm'- ing a portion of each revolutionof the roll A' y15. and gear 3 4. This intermission in theopleration'ofthe storage' roll'occurs during the raction of the cam 23 and is lforthe purpose of 'allowing the finger 20t0 center and regis- 'terthesheets 8, 9 and 10, and to allow'these sheets to remain perfectly freefor` this registration while the upper roll 14 is lifted L'outofengagement with the paper. lThissame gear-34 `is used to drive a-eratesrtheupper roller 14.

v 31,32. andy 33 at'rest during the intermission Y in theirdrive, and inorder to secure exact engagement between the teeth of the gears' 34 and33, when the'driving action is resumed,`

there is provided a short coiled sp1'ing36 which is fmounted in arecess`37 in agear' 33. This gear'is mounted on a'stud 38, the head ofwhich closes therecess 37 andthe ring [36, as one end bears againstvtha/studY "the two gears will be secured upon the resumption ofthedrive. f l Y `The storage roll 27 is driven from the gear 80 through aplunger 40 whichis mounted ece centrically in a recess in the end of theroll 27, and is pressed against a flange 41 on the gear 30,'by means ofa coiled spring 42 car- .f ried in the recess and mounted topress theplunger'l inwardly as indicated 1n Fig. 4.

The pressure between thel plunger 40 and the ygear 30 is sucient tocauserotation of the roll 27 for the purpose of winding the sheet of paper' 8as it comes through the feed roll,

but this drive may slip when necessary and is onlysufficient to wind thesheet 8 against normal resistance. lIt is only suflicient to pull thesheet 8 between the feed rolls and in this way the increasing diameterof the storage roller 27 is compensated for so that the stored sheetwill never be drawn through the feed rolls. at any greater speed thanthe other sheets.

In Fig. 8 I have shown ya machine which in general construction andappearance is similar `to the machine of Fig. l, there being a casing'50. in which are housed three paper supply rollers 51, 52, and 53, fromwhich strips 54, 55, and 56 are led over guide rollers 57 and thenforwardly vthrough a main feed roller 58 'and a secondy feedroller 59.After passing through the feed rollers the two'u'p-v V-permost stripsofpaper and 56 pass out of themachine and are torn off in theusualmanisrolled upona storageroll 59.

ner. The lowermost strip 54 passes downywardly into the forward end ofthecasing and roll rests Aupon two small rollers and 61 which are spacedfrom each other, the'roller 60 being undriven, while the roller 61 isdriven from the feed roller 58.

may be driven either by means of a gear in the usual manner orfrictionally throughV the yformation of beveled engaging surfaces at i@the ends of the rolls 58 and 61, which are 55 connected through beveleddisk 62 which env gages with the beveled surfaces on-the rollers 58 andv61.l In this manner the rollers 61 -vis rotated in acounter clock-wisedirection V'and actsto revolve the roller 59in-a clock- C5. the movementof the storage roll.

t wise directionv which-serves to throw strip 54k forwardand towinditupon'this roll, The roller'60 acts merely as a second support forthe storage roll 59 and is of course rotated by The above describedmeans `vfor operating This storage This roll 61` necessary where thestoragevroll is positively driven from the feed rolls. Y The roller 59is mounted in slots 68 and is normally held at the bottom of these slotsby means of coiled springs l64 which permit Y the upward movement oftheroller to allow paper` to pass between it and-the main feed rollY 58.The latter is flattened to form a flat surface 65 whichis`considerablybelow the `lower-most level of the roller 59 and wouldhence release the grip of these two rollers on `the paperV when this:flattened portion comes.

directly beneath-the position of the roller 59. Mounted in thisflattenedportion of the roller 58 is a pin 66,fthe outer end of which projects ito the level of the outersurface of the roller if lthe same "were notcut off. That is, this pinz66 comes into exact contact with the rollerv59 when the latter is in its lower-most position except for the-thickness of the paper sheets therebetween.

The action' of this .flattenedV face on the roller 58 and of the pin 66is substantially identicalwith the action of the pivoted finger 20 whichis shown in Figure 1.1 lVhen the v flattened face on the roller 58 comesbeneath the roller 59 the grip on the paper is releaset andthe pin 66 isthen able yto enter slots formed in the three paper stripsandrcrdinarily in substantial registration, and bring these strips intoexact-registration by bringing the forward edges of the three slots intoexact alignment.

The rotation .ofl pin 66 Vin the roller 58 maintains these slots inexact alignment until the curvedportion ofthe roller 58 has againpassedbeneath the Vroller 59 and cooperated lwith the latter toagain-gripjthe three sheets.

The continued lrotation of the .roller 58 pulls the sheets forward andthepin 66 moves out of the slotsin the several strips.. 1
